This publication presents the following reports: (1) Calculation of the higher harmonic currents from electric locomotives developed on power supply networks; formulas are given for evaluations under various conditions along with the parameters for each such state. (2) Calculation of the capacity of compensating installations and formulas for linear condensers taking into account possible overloading. Also given is distribution of condensers across the substation phases and in the power supply network. (c) Analysis of voltage interference on an AC substation with additional thyristor autotransformers; presented are the results of theoretical research on bus bars during regulation of the rectified current when controlled by supplementary transformer thyristors. It is determined that at a specific level of regulation the interfering current grows by 20- 23 percent, which can be eliminated by utilizing the reaction of the autotransformer in one of the filter control links. (4) Influence of parallel capacitance compensation upon wave form in the tractive network. (5) Experimental determination of protective action of "suction" transformers with reverse feed from dangerous and interfering action produced upon communication lines by inductive effects of the traction network. (6) Increasing economy of operation of hydraulic transmissions on diesel engines. (7) Influence of temperature and pressure of inlet air on supercharged diesel locomotives. (8) Theoretical evaluation of varying consumption of transmission fluid on diesel hydraulic locomotives and evaluation of fluid flow changes as locomotive speed changes.
